Description
【発明の詳細な説明】 本発明は自動注湯装置に関する。[Detailed description of the invention] The present invention relates to an automatic pouring device.
従来、低圧鋳造においては保持炉の溶湯中にプランジャ
一部材を進入させて溶湯ヘッドを上昇させることにより
・保持炉内の溶湯を鋳型キャピテイ内に注入するように
している。Conventionally, in low-pressure casting, the molten metal in the holding furnace is injected into the mold cavity by inserting a plunger member into the molten metal in the holding furnace and raising the molten metal head.
しかし、これは高温の溶湯中にプランジャ一部材を進入
させるため、プランジャ一部材が溶湯熱によって変形し
たり、或いはプランジャ一部材に溶湯内の異物が付着し
、プランジャ一部材の容積変化により加圧ヘッドの過不
足が生じる。このため、鋳造品の強度のばら付、或いは
鋳造欠陥を生じていた。本発明はこれらの問題点を解決
することを目的とするものである。However, because this plunger part enters the high-temperature molten metal, the plunger part may be deformed by the heat of the molten metal, or foreign matter in the molten metal may adhere to the plunger part, causing pressure to increase due to a change in the volume of the plunger part. There will be an excess or deficiency of heads. This has caused variations in the strength of the cast product or casting defects. The present invention aims to solve these problems.
